JoeLMutantE’s DIY step sequencer looks about as high-end as it gets. Dubbed the Project Stella, the rack-mountable monster was created as an antidote to standard linear interfaces -

Stella is an analog step sequencer based on an old P3 sequencer kit. It has been made trying to make some different to the standard 16 step linear sequencing of those TR-style sequencers.
It has two rounds of 16 knobs each one, and designed on an orbital/elllipse line. I have tried to randomize to the maximum the fact to add musical notes. When you see one linear step sequencer, automatically divides on a grid of four steps, and this one makes the music creation to sound very rigid. Avoiding that “griding” effect, the results is that the music is more natural and so different.
